"But wait fools, this is not my final form!!!"

All we need now is the forth to get rampaged on by Obito/whatever you want to call him now, then right before he passes on (again) he'll give Naruto the last bit of words to make him unlock his emotional barriers and reach his true potential or some BS like that.

Believe it!

edit: the trump card is Madara has one more ultimate eye-forbidden technique that will render Obito useless. Refer to the last line before the edit.
